Iwao AVE!

Looks good. Thank you, team!

Hello, The current binary requires JDK 11. https://repo1.maven.org/maven2/org/hsqldb/hsqldb/2.6.0/ It would be difficult to add JDK-8 version to 2.6.0, so please consider it when you release future versions. Thanks in advance! Iwao

It looks good to me. :) If I noticed anything, I'll open a new ticket or post message to the mailing list. Thank you again for helping me with the request!

I squashed all commits, then added an extra commit that adds the quick check to ByteDataType#typeCast(). Regarding the extra commit, it seemed to be better to do it separately rather than as a refactoring as there was no comparable check before, I also didn't apply the formatter because it wasn't applied previously.

F224: Add new syntax to specify relative date, time and timestamp in dataset

Added a quick check to avoid unnecessary regex operation

And refactoring to DataType is preferred to centralize for all, agreed? Yes. :) I have updated the branch. Please let me know if you want me to squash some commits after review.

F224: Replaced magic numbers with named constants.
